It has long been known that in addition to the N900 port of Firefox (released just 49 days ago) Mozilla have been targeting Windows Mobile, drawing ever nearer to a release. They have now decided to put the port on hold, following the news of Windows Phone 7 Series at MIX (and what that holds for Windows Mobile 6.5). "While we think Windows Phone 7 looks interesting and has the potential to do well in the market, Microsoft has unfortunately decided to close off development to native applications. Because of this, we won't be able to provide Firefox for Windows Phone 7 at this time. Given that Microsoft is staking their future in mobile on Windows Mobile 7 (not 6.5) and because we don't know if or when Microsoft will release a native development kit, we are putting our Windows Mobile development on hold."
